any 1/10th car shocks should do as you can tune them with different density oils to adjust the damping effect and you can harden or soften the springs with spacers. Btw what heli are you running (fellow heli pilot who drives aswell =P)? You might be able to use some 1/16th scale shocks of something like a Traxxas 1/16th erevo http://www.thetoyz.com/Traxxas/MINI-...sis/GPM/13855/
